Down branch fiber fabric and the fabricating method thereof

ABSTRACT

This invention relates to a kind of down branch fiber fabric, its fabricating method and device, which is characterized in that the fabric is composed of 10-100% down branch fiber and 0-90% textile fiber by weight. The processing steps include material choosing, silver feeding, twisting, winding packages, heat setting and weaving. The device comprises a raw material tank, a feeding conveyer belt, a inclined feeding conveyer belt, a adjustable ever roller, a brambly catching roller, a first subsiding room, an ever roller, a brambly dividing roller, a second subsiding room, two dust cages. The present invention makes the down fiber spinnable and weavable. It solves the problem that the down branch fiber can not be combed and drawn and drafted by the prior art of textile so that it can only be used as the fiber stuffing to make down garments, quilts, ticks and other bedding. This new fabric is applicable to make thermal woven, hoses, quilts, ticks or other bedding.

FIELD OF THE INVENTION

The present invention relates a kind of textile technology for down branch fiber, more particularly the present invention relates to a kind of down branch fiber fabric and its fabricating method.

BACKGROUND OF THE INVENTION

Feather and down are all good natural heat-retaining materials. Feather has a flat shape with parallel barbs grown on quills in rows. Down has cloud shape and can be grouped by down-feather and semi-plume, where down feather is fluffy structure and with little or no shaft, semi-plume does not have well developed barbicels, which make it soft and fluffy structure, but semi-plume has well formed shaft. For these characters, feather and down don't belong to fiber. With common technology, we can strip off barb-fiber of the feather or down-branch-fiber of the down or semi-plume from their quill or shaft to get separated barb-fiber and down-branch-fiber. Furthermore, the barb-fiber has same structure with but is coarser than the down-branch-fiber. We call the barb-fiber and down-branch-fiber both as down branch fiber thereafter. Since down branch fiber has very tiny barbules and hooks distributing equally along fiber, the down branch fiber is considered as a kind of hetero-fiber with unique nature and many merits, for example, soft, light, heat retaining, etc. However, using common textile technologies such as combing, twisting, draughting, it is hard to process down branch fibers since the natured hetero-fibers are non-crimp, fluffy, and very short, most of them are around 15 mm to 25 mm. This is why people use feather, barb-branch-fiber and down branch fiber as stuffing materials for making down garment, quilts, ticks and other bedding only.

Patent Publication Number CN1222591A titled “Down Branch Fiber Fabric and Its Fabricating Method” and Patent Publication Number CN1293270A titled “Down Shell Fabric” described a kind of fabricating method for down and down-branch-fiber fabric with textile fibers.

According to the common knowledge in the down products industry, down is not only depicted as small, soft, fluffy which is found under the contour feathers of waterfowls such as geese, ducks and the like, but also depicted as a mixture of down, feather, barb-fiber, down branch fiber and other impurity, where the ration of down must be over the lowest standard stipulated. The down described in the above-mentioned two patent publications is not a kind of material having same structure, it can't be considered as fiber too. Where, the concept of fiber is for the kind of natural or synthetic thin filiform of textile material only. Downs can't be used as textile materials for fabrication directly. If inweave downs with other textile materials, it is impossible to get a smooth and uniform yarns since down is fluffy and mixed with other impurity, such as feather and barb-fibers. During processing downs are blown away since they can't be mixed with other textile fibers as a uniform combination.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a fabricating method for down branch fiber and its products, i.e. down branch fiber fabrics with strong tensile strength.

The above-mentioned objects are achieved by:

Down branch fiber fabrics are made by mixing down branch fibers with textile fibers, having a blend ration by weight of down branch fiber 10-100%, textile fiber 0-90%.

The down branch fiber is gotten from handling downs and feathers, which are gathered from waterfowls such as geese, ducks and the like. Cut quills and shafts off from downs, semi-plumes and feathers, then get down branch fiber.

Textile fibers are selected at least one from nature fibers including cotton, wool, ramie fiber or synthetic fibers including terylene, acrylic, nylon, polyvinyl chloride, spandex, vinylon or chemical viscose fibers.

The method for producing down branch fiber having following processes: screening raw materials, sliver feeding, twisting, winding packages, heat setting and weaving. The temperature for heating setting is from 80° to 120° C., heating time is from 5 to 20 minutes.

The sliver feeding devise comprises raw material tank, feeding conveyer belt, adjustable even roller, brambly catching roller, first subsiding room, even roller, brambly dividing roller, second subsiding room. All these sub-devises are through connected. Discharging port having bar shape is connected with dust cages coincidentally.

The present invention possesses many advantages compare with common technologies in this field:

A. The sliver feeding devise has the brambly catching roller and the brambly dividing roller to comb down branch fibers twice; has the adjustable even roller and the even roller to control quota of down branch fibers well-distributed around the process; has first and second subsiding rooms to subside the raw materials twice in smooth and equal quantity to ensure that the down branch fibers can pass through the discharging port uniformly. With above-mentioned devises, the present invention solves the difficulty for processing down branch fibers, i.e. non-crimp, fluffy and can't hold together. Therefore, the difficulty for producing down branch fibers as yarns with current processing (combing, twisting, and drafting) is overcome. The present invention finds a way to use down branch fibers to produce yarns directly without a crimp treatment or a denaturation treatment. Thus, the new devices avoid breaking or damaging down branch fibers during process. Therefore, textile products made by down branch fibers are a reality.

B. Since the present invention adapts reel heat Setting, the shortcomings of down-branch fibers, such as non-crimp, restoring original shape, anti-twisting, low tensile strength, etc. is overcome.

C. Down branch fiber is a kind of nature hetero-fiber. It is light, heating-retaining. The fabrics made by this kind of nature hetero-fiber also keep these merits.

D. The present invention provides bright future to use down branch fibers to fabricate different types of pretty and decent products.
